FIELD OF THE INVENTION

The present invention relates to the field of indoor cleaning tools, and in particular to a sweeping and mopping integrated machine, by which floor sweeping and floor mopping may be completed simultaneously.

DESCRIPTION OF THE PRIOR ART

With the increasing improvement of people's quality of life, indoor cleaning becomes more and more important. In indoor cleaning, floor sweeping and floor mopping are common. At present, floor sweeping and floor mopping operations are performed separately. One needs to prepare tools for floor sweeping and floor mopping separately as well as operate floor sweeping and floor mopping separately at different time periods. There are a variety of cleaning tools prepared at home, occupying much space. Moreover, floor sweeping and floor mopping operations need to be performed separately, which is also a waste of time. In order to reduce the number of types of cleaning tools that one needs at home and to enable floor sweeping and floor mopping to be performed simultaneously for time saving, it is necessary to design a tool that can simultaneously sweep and mop the floor, so as to save space for a house and save the time taken by people in cleaning, thereby improving life efficiency.

Therefore, those skilled in the art devote themselves to developing a novel cleaning tool that may complete floor sweeping and floor mopping at the same time.

SUMMARY OF THE INVENTION

In view of the above drawbacks of the prior art, the technical problem to be resolved by the present invention is to provide a sweeping and mopping integrated machine.

To achieve the above object, the present invention provides a sweeping and mopping integrated machine, characterized by comprising a sweeping and mopping assembly, a collection assembly, a water spraying assembly, and a handle, wherein the water spraying assembly is provided on the handle or the sweeping and mopping assembly and comprises a water storage assembly and a nozzle assembly; the water spraying assembly is configured to spray, through the nozzle assembly, water or a cleaning liquid in the water storage assembly onto a working surface to be swept and mopped; the sweeping and mopping assembly comprises a motor and a drum-type working portion which is rotatable when driven by the motor; and the sweeping and mopping assembly is configured to sweep and mop the working surface and bring garbage and liquid on the working surface into the collection assembly through the rotation of the drum-type working portion.

Further, the nozzle assembly is a nozzle which is provided as a liquid outlet.

Further, the water spraying assembly comprises a manual pump or an electric pump.

Further, the sweeping and mopping assembly comprises a battery, and the motor is powered by the battery.

Further, the material of the drum-type working portion comprises cloth, sponge, felt, collodion, or fiber.

Further, the drum-type working portion is detachable.

Further, the handle comprises a gripping bend, wherein a switch of the water spraying assembly is provided at the gripping bend, and the switch is of a mechanical type or an electronic type.

Further, the sweeping and mopping integrated machine further comprises a control switch, which is provided on the sweeping and mopping assembly or the handle.

Preferably, the control switch is provided on a handle assembly.

Further, the sweeping and mopping assembly comprises an electronic control assembly.

Further, the collection assembly is detachable.

Compared with the prior art, in the present invention, it is possible to spray water through a nozzle onto a floor to be mopped, which is conductive to wet floor mopping, and with the high-speed rotation of a rolling brush, garbage may be swept into a garbage box, and excess water and garbage may also be swept into the garbage box simultaneously, such that floor sweeping and floor mopping are performed simultaneously, thereby resolving the problem that an existing ordinary mop cannot sweep garbage and an ordinary sweeper cannot mop the floor once and for all.

The drum-type working portion of the present invention may rotate at a high speed when driven by a motor, such that when a “mopping” effect is produced due to friction on a working surface such as a floor or a window, solid waste and liquid may be brought and drawn into the collection assembly with the rotational movement of the working portion and a negative pressure formed thereby, that is, a “sweeping” effect. Meanwhile, high-speed rotation may also “spin” the liquid absorbed by the working portion itself into the collection assembly, that is, a spin-drying function, such that the working portion may continuously absorb the liquid on the working surface.

Existing dust collectors cannot perform wet floor mopping, are highly noisy, and are expensive and inconvenient to use without a power cord. Sweeping robots on the market cannot mop the floor in a wet manner, among which, very few can mop the floor in a wet manner but have secondary pollution and high price. Whereas the sweeping and mopping integrated machine of the present invention may be handheld and convenient to operate, without secondary pollution when performing wet floor mopping, and the price is low.

The concepts, specific structures and produced technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the objects, features, and effects of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. For ease of illustration, in the present invention, one end, which is close to a user (or a handle) or far away from a floor, of the sweeping and mopping integrated machine is called a “proximal end”, and the other end, which is far away from the user (or the handle) or close to the floor, of the sweeping and mopping integrated machine is called a “distal end”.

As shown in FIG. 1, it is an overall schematic diagram of a preferred embodiment of the present invention. In this embodiment, a sweeping and mopping integrated machine comprises a sweeping and mopping assembly 1 and a water spraying assembly 2 on a distal end and a handle assembly 4 on a proximal end. The water spraying assembly 2, the sweeping and mopping assembly 1, and the handle assembly 4 are connected by means of a handle 3. The handle 3 is divided into a handle upper connecting rod and a handle lower connecting rod, which are connected by means of a handle connecting piece. The handle upper connecting rod is located on the proximal end and the handle lower connecting rod is located on the distal end. Specifically, the sweeping and mopping assembly 1 is connected to the water spraying assembly 2, which is connected to the handle lower connecting rod. The sweeping and mopping assembly 1, the water spraying assembly 2, the handle lower connecting rod, and the handle upper connecting rod are sequentially connected from the distal end to the proximal end of the sweeping and mopping integrated machine.

The handle assembly 4 is connected to the handle upper connecting rod. The handle lower connecting rod is connected to the handle upper connecting rod on a side towards the proximal end through the handle connecting piece and to the water spraying assembly 2 on a side close to the distal end. The water spraying assembly 2 is connected to the sweeping and mopping assembly 1 through a connecting piece. The water spraying assembly 2 may be flexibly rotated relative to the sweeping and mopping assembly 1. The user may adjust the angle between the handle and the sweeping and mopping assembly 1 by rotating the handle so as to ensure quick and easy adjustment to the most suitable and comfortable position when sweeping and mopping operations are performed. Connection between the water spraying assembly 2 and the handle lower connecting rod is a fixed connection. In a process of using the sweeping and mopping integrated machine, the water spraying assembly 2 is responsible for spraying water, which is atomized by the nozzle and falls on the floor evenly so as to keep the floor moist, while the sweeping and mopping assembly 1 is responsible for completing the floor mopping and floor sweeping operations, such that wet floor mopping and floor sweeping are completed simultaneously. The water spraying assembly 2 maintains a certain distance from the sweeping and mopping assembly 1. The sweeping and mopping assembly 1, when in operation, is attached to the floor, and the water spraying assembly 2 is fixed on the handle lower connecting rod and at a certain distance away from the floor so as to ensure that the water sprayed by the spray assembly 2 may be sprayed onto the floor instead of falling onto a surface of the sweeping and mopping assembly 1. The handle upper connecting rod is connected to the handle lower connecting rod on the side towards the distal end through the handle connecting piece and to the handle assembly 4 on the side close to the proximal end.

As shown in FIG. 2, the water spraying assembly 2 comprises a water storage assembly 201 (as shown in FIG. 3) and a nozzle assembly 202 (as shown in FIG. 4). The water storage assembly 201 and the nozzle assembly 202 are fixedly connected, wherein the water storage assembly 201 is located at an upper portion, and the nozzle assembly 202 is located at a lower portion. A lower end of the water storage assembly 201 is provided with a protrusion, an upper end of the nozzle assembly 202 is provided with an opening, and the protruded lower end of the water storage assembly 201 is inserted into the opening on the upper end of the nozzle assembly 202. In this embodiment, the two are fixedly connected by means of threads. An outer surface of the protruded lower end of the water storage assembly 201 is provided with outer threads, and an inner wall at a corresponding position inside the opening on the upper end of the nozzle assembly 202 is provided with inner threads. The water storage assembly 201 is inserted into the nozzle assembly 202 from the upper end. The outer threads of the protruded lower end of the water storage assembly 201 are riveted with the inner threads of the upper end of the nozzle assembly 202, such that the water storage assembly 201 and the nozzle assembly 202 are connected together in a fixed manner. Clean water or an aqueous washing liquid is placed in the water storage assembly 201.

As shown in FIG. 4, the nozzle assembly 202 comprises a small section of connecting rod, and the nozzle assembly 202 is fixedly connected to the small section of connecting rod. The connecting rod is a two-layer connecting rod comprising an inner rod and an outer rod. The connecting rod of the nozzle assembly 202 is fixedly connected to the handle lower connecting rod on one end and to the sweeping and mopping assembly 1 on the other end. When the water storage assembly 201 and the nozzle assembly 202 are connected together in a fixed manner, the liquid in the water storage assembly 201 may flow into the nozzle assembly 202 by making passages of the threads connected. A manual pump 203 is built in the connecting rod of the nozzle assembly 202, and there is a liquid circulation channel between the nozzle assembly 202 and the manual pump 203. When the manual pump 203 is closed, the manual pump 203 cuts off the circulation of the liquid. When the manual pump 203 is open, the liquid flows through the manual pump 203, the manual pump may apply pressure to the liquid so as to push the liquid to flow from another channel into the nozzle assembly 202 and to be sprayed out of a nozzle 204 in the nozzle assembly 202, the nozzle 204 may atomize the liquid first, and then, the atomized liquid may fall onto the floor evenly.

As shown in FIG. 5, the sweeping and mopping assembly 1 comprises a detachable transparent cover 1001, a control switch, a multi-directional rotating head 1003, a charging indicator 1004, and a roller assembly 1005.
